This webinar introduces approaches for visualising spatial-transcriptomics data leveraging the SpatialData framework together with open-source software tools such as napari  and Vitessce. It will demonstrate multiple examples for each tool, including datasets from both sequencing-based and imaging-based spatial-transcriptomics technologies. The session will provide a practical overview of how to configure, customise, and interact with visualisations in napari and Vitessce, and conclude with an overview of how these visualisations can be integrated in different stages of the analysis workflow from exploratory analyses to publication.This event is part of a broader webinar series on spatial transcriptomics.
